Sentry Smartlock Plus vs Speed Tracker Pro GPS

Give keyless convenience and the ability to configure and access your smart lock via Bluetooth.

Speed Tracker Pro helps you monitor your speed and stay within legal limits. The app turns your iPhone into a precise GPS speedometer with trip recording and speed limit warnings – reliable even in the background. FULL-CIRCLE SPEEDOMETER Large, easy-to-read speed display in km/h or mph. The animated full-circle speed arc with a green-to-red gradient shows your current speed at a glance – whether driving, cycling, or on foot. RELIABLE BACKGROUND TRACKING Unlike other speed apps, Speed Tracker Pro keeps running reliably in the background. Switch to Maps, Spotify, or other apps – your trip is recorded without gaps. Every GPS point is saved instantly so no data is ever lost. DETAILED TRIP STATISTICS Every trip is saved with average and top speed, distance traveled, moving time, a speed graph over time, and a color-coded route on the map. TRIP LOG All trips are saved automatically. Search your history, compare stats by week, month, or year, and keep track of all your routes. SPEED LIMIT ALERT Set your preferred speed limit or enter a custom value. A visual warning and haptic feedback are triggered when you exceed it. The speed limit warning is always active to help you drive responsibly. SIRI SHORTCUTS Start and stop recording via Siri or Shortcuts automation. Perfect for hands-free control. ONE-TIME PURCHASE Speed Tracker Pro is a one-time purchase. No subscription, no ads, no hidden fees. Pay once and use it forever. Note: Continued use of GPS running in the background can decrease battery life. Speed Tracker Pro is optimized for minimal battery consumption.`
